  Curves 
  were 
  drawn 
  to 
  represent 
  the 
  changes 
  in 
  the 
  density, 
  

   viscosity, 
  and 
  electrical 
  resistance 
  of 
  the 
  different 
  solutions 
  

   with 
  change 
  of 
  temperature, 
  and 
  the 
  values 
  obtained 
  from 
  

   these 
  curves 
  for 
  every 
  10° 
  C. 
  are 
  contained 
  in 
  Tables 
  I., 
  II., 
  

   and 
  III. 
  These 
  curves, 
  and 
  others 
  obtained 
  from 
  interpolated 
  

   values, 
  were 
  plotted 
  with 
  extreme 
  care 
  on 
  very 
  large 
  sheets 
  

   of 
  squared 
  paper 
  in 
  order 
  to 
  keep 
  the 
  required 
  degree 
  of 
  

   accuracy 
  throughout. 
  

  

  In 
  the 
  experiments, 
  the 
  extreme 
  temperatures 
  of 
  the 
  bath 
  

   were 
  o, 
  15 
  C. 
  and 
  98°' 
  70 
  C, 
  and 
  the 
  transpiration 
  times 
  

   varied 
  between 
  809 
  sees, 
  and 
  118 
  sees.
